SAFETY NOTICE

The electrical components inside the CASPAR compressor are properly grounded. However, it is crucial for the customer to ensure the correct grounding for the compressor to guarantee safe operation. Please note that the compressor’s grounding point is located outside of the canopy, as shown below.

CASPAR COMPRESSOR

INSTALLATION POSITION OF AIR COMPRESSOR

  1. Avoid Combustible Environments: Ensure that the machine is installed in an area free from any explosive, flammable gases (such as acetylene or propane), organic solvents, or other combustible materials.

  2. Indoor Installation Only: The compressor is specifically designed for indoor use (unless otherwise designed). Outdoor installation is strictly prohibited, as exposure to water can lead to component damage, electrical hazards, and fire risks.

  3. Protect from Electrical Surges: Install the compressor in an area without electrical surges, as disturbances can lead to electrical component malfunctions.

  4. Consider Compressor Size: When designing and installing the compressor, allow ample space for maintenance and repairs. Maintain a distance of at least 1.2 meters above the compressor’s upper part, and ensure a channel width between the unit and the wall ranging from 0.8 to 1.5 meters, depending on displacement.

  5. Proper Outlet Pipe Connection: When connecting the compressor’s outlet pipe, ensure that it is positioned lower than the compressor’s outlet to prevent condensate water from flowing back when the compressor is not in operation.

  6. Ensure Adequate Ventilation: Create a well-ventilated and clean environment for compressor installation to prevent overheating of the compressor.

MAINTENANCE--Compressor lubricant

Caspar compressors utilize various lubricants tailored to specific applications. Each compressor unit is shipped with a labeled lubricant specifying its type. These lubricants vary based on ambient temperature and load conditions, resulting in different oil change intervals. To ensure the safe and stable operation of your Caspar compressor, we recommend using Caspar genuine lubricants.

Avoid mixing oils of different types or brands, as this can lead to issues like oil blistering, filter and orifice blockages, and reduced compressor and lubricant lifespans.

While the compressor is running, regularly monitor the lubricant level. Every compressor is equipped with an oil sight glass on the oil/air tank. The standard lubricant level should fall within the green zone of the oil sight glass. If the lubricant level drops into the red zone after shutdown, the unit requires refueling. However, refueling should only be performed when the unit is completely shut down and drained.

Factors that can affect oil life include: Unusually high operating temperatures; Pollution; Usage of different lubricant types or brands; Exposure to strong oxidizing substances like acids, sulfur, chlorides, nitrogen oxides, welding fumes, ozone; Ammonia exposure; Solvent-type fumes; Airborne dust particle

MAINTENANCE--Oil filter

The oil filter cartridge of the new compressor should be replaced after every 600 hours of operation. Additionally, replacement is necessary whenever any of the following conditions occur. When replacing the filter, ensure that the unit is shut down, and meticulously clean any dirt and oil from the outside to prevent impurities from entering the lubrication system.

■ When the filter pressure exceeds 1.7 Bar (25psi) at normal operating temperature (differential pressure) and triggers an alarm. ■ Every 2000 hours of operation. ■ During an oil change. ■ When an oil sample test indicates failure.

MAINTENANCE--Oil separator

The element comprises the entire structure, and oil mist can condense on its surface, forming oil droplets that drip into the separator’s bottom. From there, the oil is returned through the oil return pipe to the compression chamber. It’s crucial to handle the separator with care to avoid any damage. Even a slight impact or indentation on the separator core can significantly impact its separation efficiency, leading to excessive oil content in the compressor outlet. Even a tiny hole in the separator can result in very high oil content.

  1. Under normal circumstances, if the air filter and oil filter are properly maintained, there is no need for periodic replacement of the oil separator filter.
  2. The oil separator should be replaced in the following situations:
  • When the pressure difference before and after the oil separator exceeds 1 BAR.
  • If the compressed air still contains excessive oil despite normal oil levels, proper loading and unloading, and a functioning oil return system.
  • Every 4000 hours of operation.

MAINTENANCE--Air filter

Daily inspections of air filters are essential.

For heavy-duty air filters, clean the dust bag daily, along with the dust cap or intake silencer chamber. In dusty environments, more frequent clean-ups are recommended. If the surrounding conditions are particularly dirty, consider relocating the compressor air intake to a cleaner outdoor air source.

Regular maintenance is required whenever the air filter vacuum switch is triggered, resulting in a pressure loss of up to 0.25 BAR and illumination of the indicator light. Inspect the air filter every 600 hours or every three months for any damage or issues with the air intake system. Under normal operating conditions, the air filter cartridge should be replaced every 2000 hours or according to the recommended replacement interval. In highly dusty environments like ceramics or cement production, more frequent maintenance and replacement may be necessary.

During each air filter service, carefully check the downstream side of the filter cartridge for dirt accumulation. If dirt is present, investigate the cause and address it promptly. Ensure an absolutely reliable seal between the air filter and the compressor suction port, whether through threaded connections, flange connections, or leather pipe connections.
